My invention has for its object al trans' .card holders of visible card liles, the said pocket being provided with terminal wings which make it possible to connect the said pocket to the body of the card holder at points located above the' upper edge of the pocket.

The purpose of this is to allow the insertion in the pocket sidewise, as well as through the top thereof, of a strip substantially higher than the pocket. t

The pocket according to my invention is characterized by the fact that its twok flaps possess complementary outlines, that is, when .two pocket blanks are placed end to end their outlines so register with each other that the extensions or projections provided at the end of a flap of one blank, providing lugs for attaching the pocket to the body of the card holder, Y correspond to complementary recesses or contractionsconsequently resulting on the other flap of the other blank, the pockets being thus obtained from a strip of transparent material without waste.

The pocket may be made in several shapes and may be attached to the body of the card holders in various ways, some examples being illustrated in the annexed drawings, in which: Y

F ig. 1 shows two adjacent pocket blanks as cut from a strip of material.

Fig. 2 is a front elevation of a card holder provided with a pocket according to the.1nvention. y

Fig. 3 is a side elevation thereof.

Fig. 4 is a rear viewvn elevation of a card holder of a modified design, illustrating another way of attaching the pocket to the card` holder. f

Figs. 5, 6, 7 and 8 partially show in a smaller scale, by way of example, some outlines of pocket blanks different from that shown 1n Fig. 1, g

As Fig. l shows, each' pocket consists of A a piece of transparent material which is separated from a vsimilar piece or blank by means l vof a single cut in the material along a line l which defines at the same time the upper edge of one pocket blank and the lower yone Y of another. Each piece or blank will then be l folded along a longitudinal line 2 so that the portion 3 above this line will constitute the forward flap, whilst the portion 4 under the folding line will form the pockets rear flap. The outline of cutting linel is such that the flap 3 results formed with two end extensions or wings 5, which correspond to recesses 6 in the flap 4p As stated, the'wings 5 are adapted for the attachment of the pocket to the card holders body 7 (Figs. 2, 3 and 4) at points above the upper edge of the main part of the front iiap of the pocket.

The attachment can'be made, for instance, by means ofmetal-sewing stitches 8 parallel to the pockets edge, said stitches passing through Lwings 5 and the card holders body,

'whilst therear iiapl ofv the pocket remains unattached. This arrangement is particu-` larly suitable for small size card holders, in which the stiffnessof the material out of which the pocket'is made'is sulicient to retain the rear flap 4 close against the card holders body .thus forming also at thevrear of the said card holder another pocket which may be highly useful for the insertion of a card or indicating strip, or both, carrying notations which do not call for permanent visibility.

In the large sized card holders it may instead be preferable or necessary to also attach the rear flap to the card holders body. This is preferably done by means of a vertically directed central stitch 9 (Fig. 4) passing through the card holders body 7 and the pockets rear flap 4. In this case it will be preferable to attach the Jfront Hap to the card holders body in suoli a manner that it may not prevent the different expansions or contractions of the two materials due to variations of temperature. p

This end may be attained by notching the card holder at each side somewhat below the position reached by the upper edges of wingsl 5, when the pocket is inserted on the card holder, as shown at 10. A vertically disposed stitch 11 is then inserted through the card holder and the flap, inV such a manner that itsv llower end l12 only goes through the flap wing, clearing the card holder, through the corresponding notch 10, while its upper end only goes through the card holder, clear- 5 ing the flap wing just above its upper edge.

In this manner the relative displacements of the card holder and pocket due to their ditl'erent thermal alterations, will be free to take place.

'Ihe Figs. 1 to 4 show the preferred out line of the cut made across a continuous strip for the separation of the pocket blanks, said outline comprising a transverse portion te"- minating at each end with an upwardly directed ninety-degrees curve and a similar outwardly directed curve terminating in a short horizontal portion. Similar results may be attained by means of cuts having different outlines, such as, for instance, those shown in Figs. 5, 6, 7, 8. In all of these, the central transverse cut has its ends directed upwardly and outwardly so as to form wings or extensions 5a, 5b, 5c, 5d in the blank severed from the strip and corresponding recesses 6a, 6b, 6c, 6d, at the ends et the lower edge of the next blank.

As stated in the course ot' the description and from the figures, a pocket having wings formed integral therewith in accordance with my invention presents the advantage of making it possible to use an indicating strip wider than the depth of the pocket, as advocated in the constructions described in my Patents Nos. 1,742,087 Dec. 31, 1929, and 1,770,793 July 15, 1930.

In the present case, however, no separate collars, and no extensions at the bottom of the card holder such as shown in some of the previous constructions are required. At the same time all waste of material, such as occurs in the production of some of the card pockets shown in my other patents above referred to, is entirely avoided.

It is obvious that minor changes and modifications may be made in the constructions described and shown, without departing from the inventive idea; accordingly, I reserve the right to carry my invention into practice in all those ways and manners which may enter, fairly, into the scope of the appended claims.

I claim:

1. The method ot producing visible index card pocket blanks, which consists in successively isolating said blanks from a continuous strip of material the width of which corresponds to the width ot the pockets to be Jiiormed from said blanks, by cutting said strip along a line comprising a central transverse portion, and two outwardly direct-ed end portions lowitudinally offset from, and connected to. said central tract.

2.
